The number of Walking Dead TV viewers in New York state in 2014 was 3,345,678. According to the TV polls, the show is losing viewers and has been decreasing by 2% per year.
a) Write an exponential decay (GET IT!! LOL) function that represents the number of viewers.
b) How many viewers will there be in 2018? Round your answer to the nearest whole body oops number!
1. A website has 500,000 members in 2010. The number y of members increases by 15% each year.

Determine whether each table represents an exponential growth function, an exponential decay function, or neither.
Determine whether the table represents an exponential growth function, an exponential decay function, or neither. Explain.
Determine whether each function represents exponential growth or exponential decay.
Identify the percent rate of change and the decay or growth factor.
a. y = 4(1.06)t b. f (t) = 24(0.83)t
Determine whether the function represents exponential growth or exponential decay. Identify the percent rate of change and the decay or growth factor.
4. y = 2(0.92)t 5. f (t) = (1.2)t
